According to the meteorological department's forecast, in the second half of this month, Shaanxi and other places will successively appear the second time since the winter, the rain, snow, cooling and freezing weather process with wide range, high intensity and long duration. In order to avoid the loss of facilities agriculture, agricultural experts have reminded large numbers of vegetable farmers to do disaster prevention work in advance.
One is to reinforce the shed body to prevent it from collapsing. It is necessary to cover the back wall of solar greenhouses with rain-proof material such as plastic film or asbestos roof to ensure that the wall is not damaged; add temporary columns in the greenhouse or greenhouse to reinforce the shed body, enhance snow pressure resistance, and prevent the shed body Occurrence of a collapse accident; check whether the shed film is in good condition, and repair the damaged part in time; tighten the lamination line to prevent the wind from removing the film.
The second is multiple coverage, strengthen insulation. Covering the straw or insulation on the outside of greenhouses shall be covered with a rainproof membrane; temporary small arches may be added to the greenhouse to cover the second film or even the third layer of film to increase the heat preservation performance; the front end of the solar greenhouse or the perimeter of the greenhouse The "apron film" is set to reduce heat loss in the room and enhance the insulation effect.
The third is to supplement the light and ensure growth. To supplement the temperature with stoves, electric stoves, electric lights, electric hot lines, etc.; supplement the ground temperature with the use of ground heating lines, floor heating pipes, etc.; supplement light with lights, biogas lamps, etc. The best conditions for the best installation of vegetables to fill the temperature fill light to ensure the minimum demand for the growth of vegetable crops.
The fourth is to control humidity and pay attention to disease prevention. To reduce or stop watering, so as not to reduce the temperature inside the shed to increase the humidity; disease prevention agents should also use aerosol or dust agent, so as not to increase the air humidity.
The fifth is to clear the snow cover and make timely deductions. The snow on the shed body and the snow on both sides of the shed must be cleared in time to reduce the pressure on the shed and prevent the loss of large amounts of heat during the snowfall to reduce the temperature inside the shed. After the snow has stopped, timely remove the coverings such as straws and curtains to make the vegetable plants see the light; after the rainy and snowy weather suddenly turns to be clear, the grass curtains should be partially uncovered or the insulation should be rolled up in half, and not all be uncovered until the plants are ready. After getting used to light, you can switch to normal management.

A laser hair growth cap, also known as a laser hair therapy cap or laser hair regrowth cap, is a wearable device that uses low-level laser therapy (LLLT) to stimulate hair growth. It is designed to treat hair loss and promote hair regrowth in individuals experiencing hair thinning or balding.
The cap contains multiple laser diodes or LEDs that emit red or near-infrared light. When the cap is worn on the head, the lasers or LEDs penetrate the scalp and stimulate the hair follicles. This stimulation promotes blood circulation, increases cell metabolism, and triggers hair growth.
Laser hair growth caps are typically used for a specified duration per session, usually around 20-30 minutes, a few times per week. The treatment duration can vary depending on the individual's needs and the specific cap model.
It is important to note that laser hair growth caps are not a guaranteed solution for hair loss, and results may vary from person to person. They are often used in conjunction with other hair loss treatments, such as medications or topical solutions, for more comprehensive results.
